<h2><u>Given</u><u>:</u><u>-</u></h2>

${ \large{➢ \: \: \bf{x = - 8}}}$

<h2><u>Solution</u><u>:</u><u>-</u></h2>

${ \large{➢ \: \: \bf{ \dfrac{2y}{3} = 3 \times - 8 + 34}}}$

${ \large{➢ \: \: \bf{ \dfrac{2y}{3} = - 24 + 34}}}$

${ \large{ \bf{ ➢ \: \: \cancel{2}y = 3 \times { \cancel{(10)} {} \: \: ^{5} }}}}$

${ \large{ \therefore{ \bf{y = 15 \: \: Ans.}}}}$

Find the value of x. Round the length to nearest tenth.

Lady_Fox [76]

From the law of sines, we have

$l = h\sin(\theta) = h\cos(\alpha)$

where $l$ is the leg we're interested in, $h$ is the hypothenuse, $\theta$ is the angle opposite to $l$ , and $\alpha$ is the angle between $l$ and $h$ .

So, in the first case, we can use

$x = 15\sin(35) \approx 8.6$

And in the second excercise, we use

$x = 11\cos(44) \approx 7.6$

Can someone help me with this question please

Zarrin [17]

Answer:

Step-by-step explanation:

y+ 20= x+ 15( Vertically opposite angles)

y+ 20- 15= x

x= y+ 5 __(1)

3x+ 5=4y- 15

Substituting (1)

3(y+5)+ 5= 4y-15

3y+15+5=4y- 15

y=15+20

y= 35

x= 40

Simplify:-6+{14+2[60-9(1+3)]}

yuradex [85]

1 + 3 = 4;
9 x 4 = 36;
60 - 36 = 24;
2 x 24 = 48;
14 + 48 = 62;
-6 + 62 = 56.

The table shows the values of a function f(x).

QveST [7]

Answer:

The average rate of change is $=-4$

Step-by-step explanation:

The average rate of change from x=a to x=b of f(x) is given by;

$=\frac{f(b)-f(a)}{b-a}$

We want to find the average rate of change of the function represented in the table from x=-2 to x=2.

$=\frac{f(2)-f(-2)}{2--2}$

From the table f(-2)=25 and f(2)=9

The average rate of change from x=-2 to x=2 is

$=\frac{9-25}{2--2}$

$=\frac{-16}{4}$

$=-4$
